Abstract: Disclosed is a method of washing a grain-based substrate, such as a spent grain germ. The grain-based substrate is contacted with steam and maintained in contact with steam for a time and at a pressure sufficient to liberate at least a portion of one odor component present in the substrate. Subsequently, at least a portion of the steam and at least some of the liberated odor component is separated from the balance of the substrate, thereby leaving a washed substrate. An additive, such as a soap or detergent, may be used in connection with the washing step. The grain-based substrate may be used in connection with an animal litter. In one embodiment, a litter is prepared from distiller's dried grain. Surprisingly, washing of the dried grains in accordance with the preferred teachings reduces the odor of the distiller's dried grains and yields a litter with excellent clumping properties.

Title: Rendering of subsurface scattering effects in translucent objects
Inventor: TARTAGLIA BRUCE NUNZIO
IPC: G06T15/50
Filed: 2009-03-26
Abstract: Embodiments are directed to modifying an existing scheme for providing translucent illumination in order to take account of subsurface scattering. The color of a selected point of a translucent object can be determined using existing methods. The existing methods need not take subsurface scattering into account. Then, a contribution to the color at the selected point due to subsurface scattering may be calculated. The contribution due to subsurface scattering may be calculated based on a photon map. Embodiments of the invention also include the use of different types of photon maps. In some embodiments, a standard photon map may be used. In other embodiments, a photon map may be defined in a manner similar to a depth map. Thus, the entries of a photon map may be defined in terms of an angle from a light source and a distance between an object's surface and a light source.
